UNITED STATES PATENT OFFICE.

JOHN W. GRAVES, OF OOVINGTON, TENNESSEE, ASSIGNOR TO INTERNA- TIONAL COTTON COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORA- TION OF SOUTH DAKOTA.

BALlNG-PRESS.

Specification of Letters Patent.

Patented March 5, 1907.

Application filed October 12, 1904. Serial No. 228,194.

citizen of the United States, and a resident of Covington, in the county of Tipton, in the State of Tennessee, have invented certain new and useful Improvements in Baling- Presses, of which the'following is a full, clear, and exact description.

This invention is in the line of balingpresses in which the cotton fiber is compressed into a wad by means of rollers and forceddown upon the press-platen until a sufficient quantity thereof has been accumulated to compose a bale.

The object of this invention is the effecting of means whereby the pressure engendered by thus forcing the cotton wad down upon the press-platen shall be utilized to operate one or more other presses containing the bales previously compressed to a certain extent in the first press.

I further design to form a baling-press in which the pressure in the first press shall he intensified to a considerable degree in its efiect upon the supplemental presses.

Referring to the drawings forming part of this specification, Figure 1 is a side elevation, the right-hand half in section, of a balingpress embodying my invention. Fig. 2 is a plan view of the same. Fig. 3 is an end elevation of the press. Fig. 4 is a sectional side elevation through the line 1 1 in Fig. 1. Fig. 5 is a similar sectional view, but on the line 2 2 in Fig; 1. Fig. 6 is a horizontal section on the line 3 3 in Fig. 1. I Y

My complete machine is preferably composed of three presses, the central one being the primary. and the others the secondary presses. These presses are each of the hyraulic type, although employing oil in place of water, each comprising a cylinder, a piston, and a platen carried by the iston; Above the primary press, whose cy inder is designated by the reference-letter E, are located the packing-rolls G H, which are reciprocated in substantially the usual manner for the purpose of properly laying the wad upon the growing bale. The platen t of the primary press is shown in Fig. l as provided with a carriage w movable on ways W W to the secondary press-platens 0 p.

The cylinder E is connected by suitable pipes m n to the secondary cylinders M and N, respectively, each such pipe being provided with a pressure-valve m and n and a by-pass section U and V, closed by a cook a and v.

As the platen tis forced downward under the pressure of the Wad being laid by the rollers G H the oil in the cylinder E passes to the cylinders M N. The secondary pistons O P 1 are of a much larger area or cross-section than the piston in the primary cylinder, as best shown in Fig. 6, and the pressure communicated to said pistons O P will therefore be much greater than that originally imparted to the platen t.

A further improvement consists in providing the piston T of the primary press with a sleeve 1t, whereby the pressure communicated to the secondary cylinders ma be varied, for it is evident that when said s eeve is fastened down and the piston alone depressed from its elevated position the pressure communicated will be much larger than when both sleeve and piston are forced down together.

The operation of this baling-press is as follows: Having turned the cock u wide open, oil is pumped through the pipe m until the platen and carriage t 10 reach the rollers G H,

the piston or plunger 0 being so much heavier than the other as to remain down and the cock o being closed. The cook it is now closed and the pressure-valve m set at preferably seven hundred and fifty pounds, and the pressure-valve a set at a somewhat greater pressure. The rolls G H being put into operation, the cotton wad is laid in the sacking placed on the platen, continuously forcing down said platen until the bale is formed. This descent of the piston and sleeve T R forces the oil over into the cylinder M, raising the piston O the slight distance of which the quantity of oil in the larger cylinder is capable. This formed bale is then moved over to the platen p, being conveyed on the carriage 10 and another carriage placed upon the platen 25. By opening the cock u the weight of the piston and platen O o forces the oil over to the cylinder E and elevates its piston and platen. Then the cook a is closed and the pressure-valve 12, set at seven hundred and fifty pounds and the valve m at an excess above the same, after which another bale is formed on the platen t, thereby giving a first compression carriage up to the rollers G H.

to the bale placed over the platen 10, since, as is evident, the oil beneath the primary piston must pass to the piston P and force it upward, while any excess of pressure in forming the bale on the primary platen over and above the seven hundred and fifty pounds escapes through the other pressure-valve m, This second bale thus formed is moved along to the ways WV between the platens t and 0, the sleeve or ring R fastened down, the cock it opened, and the weight of the piston and platen of the secondary cylinder M permitted to raise the piston and platen T t to their elevated position, a new carriage 212 being of course first placed thereon and oil having been pumped into the cylinder M until the piston T is raised to bring its platen and Having changed the pressure-valves n m to twelve hundred and fifty pounds and to an excess thereof, respectively, another bale is formed on the primary platen and the pressure thereof caused to give the increased pressure above named to the bale already once compressed on the platen 1). Following this the cock 1) is opened, the sleeve or ring R locked to the piston T, the weight of the piston P caused to elevate the primary platen 25, the bale on the platen p tumbled off, the pressure-valve m set to seven hundred and fifty pounds and the valve n to a larger pressure, and another bale formed upon the primary platen, and thereby giving a first compression to the bale which had been laid upon the ways WV, but has been later placed upon the platen 0. From this point onward the operation is a mere repetition of-what has already been described.

The detailed construction of this balingpress is as follows: A B are the foundations supporting the cylinders M N C C c w a 7c K D L L b b d d, iron beams composing the framework of the machine. The rollers G H are supported by the member F, slidable in ways f, with friction rolls f above said member. This member or carriage is recipprocated through the agency of the pitmen 7' taking its motion from the crank-arms i on the shaft J, power being communicated to said shaft by means of the pulley j.

The rollers G H rotate in unison by means of the intermeshing gears g It, the roller G having fixed on its shaft a bevel-gear g, with which meshes a bevel-gear g slidable on the shaft 9 The said small gear g is retained in mesh with the large gear 9 by means of suitable bearings g, rigid with the roller-can riage F. The shaft g is further supported in bearings g g and rotated by power delivered to the pulley I. This arrangement enables the rollers to be forcibly and continuously rotated while being reciprocated.

To facilitate the removal of bales from the primary to the secondary presses, frictionrolls k Z a and b are provided, each set being rotatively supported immediately above the bales in the roof-sections 10 P, a, and b, respectively.

The cylinder-casings a b are rigidly connected with the upper members a? b of the respective presses by the tie-rods a I), while the primary press-cylinder E has its supporting beams d d joined to the beams D c by the tie-rods d and caps d The means whereby the sleeve or ring R is locked from rising with the piston T consists of the swinging latches or hooks s pivoted to the head S of said sleeve at s and constructed to be engaged by the projections e of the casting e. Said sleeve is of course provided with a packing 8 near its upper end to pre vent leakage of the oil within the cylinder.

The oil to be originally introduced into the press-cylinders is pumped through the pipes m or n, as also to replace that lost through leakage.

The construction of the devices for the forcibly-operated bale-forming means is not specifically claimed in this application.

What I claim as my invention, and for which I desire Letters Patent, is as follows, to-Wit:

1. In a baling-press, the combination with a forcibly-operated bale-forming means, and a platen, piston and cylinder cooperating therewith, of a secondary press operated by the depression of the said piston.
